The invention relates to an assembly device for assembling camshafts, comprising a holding device for axially fixing individual elements such as cam discs, bearing seats or gears, including a pressure agent probe for hydraulically expanding a hollow shaft in sections, with the elements and the shaft being connected to each other in a force-locking way. The holding device has been provided with individual fixing discs each having a central aperture for receiving one of the elements such as cam discs, bearing seats or gears as well as an outer bearing seat for being received in a bearing region of the holding device. These fixing discs permit angularly accurate fixing of the individual elements prior to assembly, with the hollow shaft being able to carry out radial movements relative to these.
